FIELD OF INVENTION

This invention relates to a temperature-controlled baby cradle, or bassinet. More specifically, the invention relates to a temperature-controlled baby cradle, or bassinet, that maintains a low temperature for extended preservation of a baby or infant who has died.

BACKGROUND OF THE DISCLOSURE

The loss of a baby, or infant, can be devastating for the parents. The death of a baby can be classified in two main areas—a pregnancy loss or an infant death. A “pregnancy loss” may be defined as a stillbirth, which is the birth of a baby, or infant, who has died in the womb any time after 20 weeks gestation (considered the age of fetal viability). The causes of death can range from, but are not limited to, genetic disorders, maternal disorders, placenta problems, cord knots or compressions, injury to the mother, injury to the baby, illnesses, and in some cases there are no known causes. “Infant death” refers to any baby who survived birth up through one year of age and then passes for any reason. Causes include, but are not limited to, congenital abnormality, prematurity, injury, illness, SIDS, accident, or other various causes.

Stillbirth is one of the most devastating of losses, affecting over 25,000 families each year. Stillbirth affects families of all races, religions, and socio-economic status. For many parents, stillbirth is a loss that hit unexpectedly—up to half of all stillbirths occur in pregnancies that had seemed problem-free.

Parents in these circumstances often desire an extended period of time to grieve the loss of their child in a comfortable, unhurried setting. However, past methods of addressing the matter have fallen short. Often the deceased baby is quickly removed to a morgue or stored in a cooler, or refrigeration device, in the hospital, such as a neonatal care unit. This interrupts the grieving process and lacks sensitivity. Using ice packs, dry ice, or chilled rice bags are a short-term solution, requiring restocking or re-chilling and sometimes the use of harmful chemicals, and result in significant temperature fluctuations and wetness due to melting. Similarly, turning the temperature down in the entire room is a short term solution that leads to temperature fluctuations and can make the entire room uncomfortable.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

In various exemplary embodiments, the present disclosure comprises a temperature-controlled baby apparatus or device. In several embodiments, the apparatus comprises a cart 10, having a frame 14 with a cradle 20, or bassinet 20, a compressor system 44, a copper coil surrounded with an aluminum finned condenser unit 46, heat exchanger 48, evaporator 50 and base plate 30, drain pan 52, power supply conduit 54, and a thermostat 42 that will comprise the cooling unit 40 for the cart 10.

The unit 10 is preferably self-contained, mobile, and can be self-powered (e.g., battery) or powered by an electrical cord plugged into a standard power supply (e.g., 115V, 230V, or other standard voltage as used in various parts of the world). Operation is quiet or semi-quiet (as opposed to prior art devices which can be loud and noisy), and there are no exposed wires or hoses, and no harmful chemicals. The temperature in the cradle 20 is maintained at a constant temperature inside the room with the parents, allowing the parents to spend an extended period of time with the baby without requiring an adjustment in the temperature of the entire room. In the embodiments, the present invention can run constantly, or cycles on only as needed to maintain the desired temperature. The device thus provides parents and families a solid foundation to begin the grieving and healing process.

As seen in the Figures, in one exemplary embodiment, the invention comprises a mobile cart 10 with movement devices, such as wheels 12. The wheels 12 may be adjustable in height. Similarly, the cart 10 may be adjustable in length, width, and height. The cart 10 may be collapsible or foldable along one or more joints or connections. The cart 10 can include a frame 14 with a plurality of panels 16 positioned to contain the cooling unit 40. The panels can have integrated doors 18 and a vent 15. The frame can include one or more handles 13.

A bassinet 20, or cradle 20, operatively engages, such as sits proximate to, on or within, a cooler or evaporator 50 with base plate 30, which is part of and attached to a cooling unit 40. The cradle 20 includes a thermally conductive bottom 22 to facilitate the engagement to the cooling unit 40. The cooling unit 40 includes a compressor system 44 and condenser unit 46 and may comprise a condenser fan with filter dryer.

Temperature can be controlled with a thermostat 42, such as, but not limited to, a digital thermostat 42. The cooling unit 40 provides for an even temperature to be maintained in the bassinet 20, thereby trying to slow and reduce physical or visual changes occurring in the baby during the grieving process. In several embodiments, the thermostat is installed directly onto the base plate 30 of the evaporator 50 with one or more temperature sensors on or inside the bassinet 20 to ensure an exact and even environment. Temperature can be adjusted as desired, allowing maximum stability for the unit regardless of surrounding environmental conditions.

A drain pan may be placed below the evaporator base plate 30 to collect any type of moisture buildup from operation of the evaporator base plate 30(such as from changes in temperature of the base plate 30, changes in temperature of the room, cycling of the thermostat 42, or shut-off of the unit). This prevents spillage of fluids in the room. A drain tube or pipe may be routed to the compressor unit 46, where moisture is evaporated due to heat from the compressor 44 and/or the evaporator 50, so that there is never any need to empty or drain the unit.

In another embodiment, the evaporator base plate 30 may be fixed in a permanent location (such as the top of a cabinet or table), with the bassinet 20 removably placed therein. The bassinet 20 also may be fixed in or on the evaporator base plate 30.

In several embodiments, the unit may use various types of Freon known in the market, or that may be developed in the future. In one embodiment, the Freon used is R134a(1,1,1,2-tetra-fluoraethan), which is a single hydrofluorocarbon with no chlorine content and no ozone depletion potential. Other forms of coolant may be used.

The cart 10, or unit 10, or components thereof, may be easily reduced or expanded in size. The bassinet 20, for example, may be modified in length, width, height and depth as needed to accommodate babies of different sizes. The cart 10, as described above, also may be similarly modifiable in size and dimension. The cart 10 and bassinet 20 each may be independently modified as needed. Spring clips may be used along sides or joints of both, thereby allowing either the cart 10 or bassinet 20, to be expanded or reduced in dimension within seconds.

Thus, it is seen that the apparatus and methods disclosed herein achieve the ends and advantages previously mentioned. Numerous changes in the arrangement and construction of the parts and steps will be readily apparent to those skilled in the art, and are encompassed within the scope and spirit of the present disclosure. Further, the particular embodiments previously described are not intended to be construed as limitations upon the scope of this disclosure.
